ADHD, the quiet type: when your child doesn't fidget but daydreams

When people think of ADHD, many picture wild, fidgety boys. But there's a quiet form that often goes overlooked for years, especially in girls.

The picture of ADHD is usually loud: a child who can't sit still, talks over others, whirls through the room. That picture exists, but it's not the whole story. There's a quiet form of ADHD that stands out not through movement but through absence, and that's exactly why it's often overlooked.

Three presentations

Professionals distinguish three presentations of ADHD: predominantly hyperactive-impulsive, predominantly inattentive, and a combination of both. The predominantly inattentive form is the quiet one: the child doesn't fidget, they daydream. They're dreamy, forgetful, often elsewhere in their thoughts, lose things, don't make progress on tasks, seem “absent". They disturb no one, and that's exactly the problem.

Why the quiet ones slip through

A child who disrupts stands out and gets attention, even if it's negative at first. A child who quietly daydreams slips through the net. They're seen as “dreamy", “slow" or “lazy", while inside they struggle with attention just as much as the fidgety child. Studies show this quiet form occurs more often in girls and is one reason girls with ADHD are often recognised late. This “quiet" is very deceptive from outside too, because the hyperactivity in this supposedly quiet type very often happens in the head. Thinking goes very fast and non-stop, jumping from one thought to the next. There's never quiet in the head. Stimming also looks much quieter in them. They don't run around wildly. They might only move their fingers a little, or twist and play with their hair or make other small, very inconspicuous movements.
